Ninety-two patients with a pulsating abdominal mass and suspected abdominal aortic aneurysm (AAcA) were examined by ultrasonography. We diagnosed 48 cases (52%) of AAA and 5 unexpected lesions ventral to the aorta (5%), but in 39 cases (42%) we were not able to explain the symptom in spite of extensive diagnostic efforts and follow-up. Changes of the aorta or transmission of the pulse by adjacent structures are the main cause of a pulsating abdominal mass. Ultrasound examination appears to be optimal screening method for diagnosing AAA as well as the other symptoms no further diagnostic efforts are necessary after a negative ultrasound study.
对92例有腹部搏动性肿块且疑似腹主动脉瘤（AAcA）的患者进行了超声检查。我们诊断出48例（52%）腹主动脉瘤以及5例主动脉前方意外病变（5%），但尽管进行了广泛的诊断和随访，仍有39例（42%）患者的症状无法解释。主动脉的改变或相邻结构传递的脉搏是腹部搏动性肿块的主要原因。超声检查似乎是诊断腹主动脉瘤的最佳筛查方法，对于其他症状，超声检查阴性后无需进一步诊断。
